Pouya Alijanipour, Dylan Greif, Nathan H. Lebwohl & Joseph P. Gjolaj
doi : 10.1007/s00586-019-06105-y
Pages: 127 - 132
Isolated vertebral transverse process fractures of thoracolumbar spine without other vertebral injuries and neurological deficit are generally considered as minor injuries with no concern for associated spinal instability. This report describes a case of multiple lumbar transverse fractures associated with an unexpected yet clinically significant spinal instability.

Opioid-sparing multimodal analgesia with bilateral bi-level erector spinae plane blocks in scoliosis surgery: a case report of two patients
Ki Jinn Chin, Michael J. Dinsmore, Stephen Lewis & Vincent Chan
doi : 10.1007/s00586-019-06133-8
Pages: 138 - 144
Postoperative pain following scoliosis correction surgery is severe and usually requires prolonged intravenous opioid therapy. Regional anesthesia options are limited and include intrathecal opioid and epidural analgesia; however, they remain little used because of side effects and inconsistent efficacy. We describe a novel multimodal anesthetic regimen incorporating bilateral bi-level erector spinae plane (ESP) blocks together with a combination of several evidence-based intraoperative opioid-sparing analgesic strategies.
Total en bloc spondylectomy of T11 and spine shortening performed on a 17-month-old patient: art of the possible
Laurent Coubeau, Cecile Boulanger, Frederic Lecouvet, Mo Saffarini & Xavier Banse
doi : 10.1007/s00586-019-06238-0
Pages: 145 - 148
The authors used spine shortening as an alternative strategy to intercalary graft fixation to restore permanent spine stability for a 17-month-old infant who received total en bloc spondylectomy (TES) of T11 to treat an embryonic rhabdomyosarcoma. TES involves complete removal of vertebra, compensated by spine reconstruction using intercalary allografts and permanent posterior instrumentation, which is not possible for skeletally immature patients with high growth potential and non-ossified vertebrae.
Occult thoracic disco-ligamentous Chance fracture in computed tomography: a case report
Daniel Garc?a-Pérez, Irene Panero, Alfonso Lagares, José A. Alén & Igor Paredes

We report on a 46-year-old woman who was involved in a road traffic accident. Neurological examination demonstrated paraplegia, while initial CT showed bilateral pneumothorax and hemothorax, rib fractures, a C2 vertebral body fracture with C2–C3 dislocation and active arterial bleeding at the sacral level. Given the fact that her neurological status did not particularly correspond with what we observed on CT scan, MRI was obtained due to the suspicion that a much more severe occult injury could be present.

doi : 10.1007/s00586-020-06595-1
Pages: 2941 - 2952
The American Society of Anaesthesiologists' Physical Status Score (ASA) is a key variable in predictor models of surgical outcome and "appropriate use criteria". However, at the time when such tools are being used in decision-making, the ASA rating is typically unknown. We evaluated whether the ASA class could be predicted statistically from Charlson Comorbidy Index (CCI) scores and simple demographic variables.

Three-column osteotomies (3-CO) have gained popularity in the last decade as part of the armamentarium for the surgical correction of sagittal imbalance in patients with adult spinal deformity (ASD). Three-column osteotomies in the form of pedicle subtraction osteotomy (PSO) may be necessary to achieve adequate correction for severe and rigid spinal deformity. Studies reporting improvement in health-related quality of life (HRQOL) with validated outcome measures after PSO surgery are sparse and currently consist of small series.

Surgery with radiation therapy (RT) is more effective in treating spinal metastases, than RT alone. However, RT when administered in close proximity to surgery may predispose to wound complications. There exist limited guidelines on the optimal timing between RT and surgery. The purpose of this systematic review is to: (1) address whether pre-operative RT (preop-RT) and/or post-operative RT (postop-RT) is associated with wound complications and (2) define the safe interval between RT and surgery or vice versa.

Composite PEEK/carbon fiber rods in the treatment for bone tumors of the cervical spine: a case series
Stefano Boriani, Valerio Pipola, Riccardo Cecchinato, Riccardo Ghermandi, Giuseppe Tedesco, Maria Rosaria Fiore, Francesco Dionisi & Alessandro Gasbarrini
doi : 10.1007/s00586-020-06534-0
Pages: 3229 - 3236
Radiotherapy (RT) is frequently applied as an adjuvant therapy during spinal tumors treatment. Metallic implants can interfere with RT planning and execution, as it is known that metallic implants produce a backscattering effect that can limit RT accuracy and their presence can be associated with unwanted dose increase. PEEK/carbon fiber implants are designed to reduce these problems but their application in the cervical spine is limited, due to the reduced number and types of implants, the screw dimensions and the absence of lateral mass screws. We propose a hybrid system made of carbon rods and screws coupled with subliminal polyester bands with titanium clamps. We designed this hybrid construct to enclose the cervical region in the area of instrumentation without limiting the application of postoperative radiotherapy.
